Energy Resources (Easy)

Which of the following is a renewable energy resource?

• Coal

• Oil

• Wind

• Natural Gas

Answer explanation

Wind is a renewable energy resource because it is generated from natural processes that are continuously replenished. In contrast, coal, oil, and natural gas are fossil fuels that deplete over time.

Which of these is a nonrenewable resource?

• Solar

• Biomass

• Geothermal

• Coal

Answer explanation

Coal is a nonrenewable resource because it forms over millions of years from decomposed plants and cannot be replenished on a human timescale. In contrast, solar, biomass, and geothermal are renewable resources.

What do we call energy sources that can be replaced quickly and naturally?

• Renewable resources

• Fossil fuels

• Batteries

• Nuclear waste

Answer explanation

Energy sources that can be replaced quickly and naturally are called renewable resources. Unlike fossil fuels, which take millions of years to form, renewable resources like solar and wind energy are sustainable and replenished naturally.

Which energy source is made from plants, food waste, and other living things?

• Biomass

• Oil

• Uranium

• Coal

Answer explanation

Biomass is an energy source derived from organic materials like plants and food waste, making it the correct choice. In contrast, oil, uranium, and coal are fossil fuels or minerals, not derived from living things.

The main reason fossil fuels are nonrenewable is because:

• They take millions of years to form and cannot be replaced quickly.

• They are found only in certain countries.

• They are used mainly for transportation.

• They are inexpensive to extract.

Answer explanation

Fossil fuels are considered nonrenewable because they take millions of years to form and cannot be replaced quickly, making their supply limited compared to the rate at which we consume them.

Which of these resources is used in solar panels?

• Wind

• Sunlight

• Uranium

• Oil

Answer explanation

Solar panels convert sunlight into electricity. Therefore, the correct resource used in solar panels is sunlight, as it is the primary energy source for their operation.

What do we call harmful gases released when fossil fuels are burned?

• Vitamins

• Greenhouse gases

• Oxygen

• Hydrogen

Answer explanation

Harmful gases released from burning fossil fuels are primarily known as greenhouse gases. These gases, such as carbon dioxide and methane, contribute to global warming and climate change.

What kind of energy comes from moving water, like rivers or dams?

• Solar

• Geothermal

• Hydroelectric

• Wind

Answer explanation

Hydroelectric energy is generated from the movement of water, such as in rivers or dams. This type of energy harnesses the kinetic energy of flowing water to produce electricity, making it the correct choice.

Which resource is burned in power plants and made from ancient plants and animals?

• Coal

• Wind

• Water

• Sunlight

Answer explanation

Coal is a fossil fuel formed from the remains of ancient plants and animals, making it the correct answer. Unlike wind, water, and sunlight, which are renewable resources, coal is burned in power plants for energy.

What do we call fuels like coal, oil, and natural gas that come from underground?

• Fossil fuels

• Clean energy

• Wind power

• Recyclables

Answer explanation

Fossil fuels are natural resources like coal, oil, and natural gas that are formed from the remains of ancient plants and animals buried underground. They are a primary source of energy but are not considered clean energy.
